Solution

1. Preparation

Gather tools: multimeter, OBD-II scanner, screwdriver set, wire connectors, and electrical tape.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect and Replace Door Switches

Remove the door panel to access the door switch:
- Use a screwdriver to remove screws securing the panel.
- Carefully pry off the panel using a trim tool.
Disconnect the electrical connector from the door switch.
Test the switch with a multimeter to ensure it opens and closes properly. Replace if faulty:
- If defective, install a new door switch by connecting it to the harness and securing it in place.
Reassemble the door panel.

3. Check Wiring and Replace as Necessary

Inspect the wiring harness for fraying or damage:
- Use electrical tape to repair any minor damage or replace sections of wire if severely damaged.
Ensure all connections are secure and free from corrosion.

4. Inspect Interior Light Switch

Locate the interior light switch (usually near the overhead console).
Ensure the switch is not set to the "on" position. If it is faulty, replace it with a new switch.
Reconnect the battery terminal.
